My instinct is to go for the cheapest, because I am cheap, and I figure it is good enough (cheapest is the dh710) anyone got an opinion? What is the difference and is there one that I am leaving out? I was looking at this site here is this a good suplier, is it a good deal? is it reputable? Any help would be a huge help. I would prefer the cheapest unless i will regret it later. Thanks a ton in advance
